The Lowdown
Alright, Rusty here, giving you the lowdown on Jaconé. We got a good stretch of surf coming, so let’s break it down.
The start of the week is where it’s at. Tuesday morning brings a 5-foot south swell with a 10-second period and a light 10 km/h offshore breeze out of the northeast. The water is 73°, right about average. The energy is moderate but solid. It should be clean. This spot can get crowded sometimes, so paddle out early.
Tuesday afternoon, the wind goes cross-offshore and the swell drops a touch to 5 feet.
Now, Wednesday the 9th is the real gem. We’ve got a bigger 7-foot swell from the east-northeast, and the wind goes completely glassy in the morning. Dead calm, 5 km/h. That’s a recipe for perfect conditions. The period is a short 7 seconds, so it’ll be a bit lumpy and less powerful, but the energy is still strong. This one’s for the confident lot.
Thursday the 10th cleans up with a smaller 3-foot south groundswell and a nice long 12-second period. Light cross-offshore winds keep it tidy. A solid option for everyone.
Friday the 11th is another cracker. You got 4-foot south swell, a very long 14-second period, and zero wind in the morning. Pure glass. The energy is pumping hard. With that long period, the waves will wrap around, but at a beach break they can get a bit walled up.
The weekend turns sloppy. Saturday the 12th is a bust with dropping swell and onshores. Sunday the 13th bounces back in the morning with a clean 6-foot south-southwest swell, but it gets messy later.
Next week is mixed. We get a few good windows, like Friday the 18th with a clean 6-foot south swell and a strong 20 km/h offshore wind. That’s a powerful, clean session.
After that, the end of the forecast gets smaller and less consistent. There’s a few small, clean days around the 22nd and 23rd, but the energy is weak.
So, your best bet is Wednesday morning the 9th. That 7-foot swell with glassy conditions is an easy call. Friday the 11th is a close second for the sheer quality of that long-period groundswell. Get out there.
Rusty.

Information about the Jaconé Surf forecast
The above surf forecast table for Jaconé provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Jaconé can be found by selecting the local surf guide option on the grey menu. Our Jaconé surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Jaconé) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Jaconé may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
